myTouch 3G OTA updatemyTouch 3G OTA update

We're getting word that T-Mobile myTouch 3G users are seeing an over-the-air (OTA) update roll in, but unfortunately it's not an update to Android 2.0/2.1 or anything. It's looking like it's not much more than a radio fix (better 3G, anyone?), but that's nothing to scoff at, either. Sing out if you're seeing anything different. [T-Mobile forums via @tsuranoth]
